[sdiy] oscilloscope considerations

[tpaddock at seanet.com]

If I was going to buy one reasonably priced scope for 
general use, I'd get analog. Digital can't be beat for 
some things, especially single shot stuff and waveform
documentation, but I would not want be digital only. 

For audio, it's useful (well, it's fun anyway) to do XY 
mode. Not all digitals can do XY. (I think) The Tek 3200's 
have a "triggered XY". But it looks "funny" to me. 

Another feature I think is underrated is GATE OUT. Gives 
you a pulse when the scope triggers. Good as a deluxe 
trigger for a frequency counter.

Modern product life cycle times are getting shorter all the 
time too. Tek no longer supports their 2400 series, which 
is a scope I like a lot. Creeps.

All I have myself is an old Heathkit. The weird thing is the 
trace fades out in XY mode. Any ideas?
